Emergency doctor Nina is certain: the laceration of her patient Ms. Ahrens is a result of domestic violence. But their team's minds are elsewhere: When they find out that they are the slowest team in the entire Mannheim fire department, they don't want to let it slide. But training for the Fire Fighter Challenge culminates in an argument because Billy, as the only firefighter in the force, doesn't want a special role. Colleague Paul finds out about Nina: Nina obviously finds it fundamentally difficult to draw a line between professional and private life. Nina not only continues to care for Emily, but also wants to save Mrs. Ahrens, the alleged victim of domestic violence, from her husband. But what if the woman doesn't want to accept help at all? The boundaries within the team are also falling. Because Nina actually didn't plan on starting anything with a firefighter.
